ieferring to the draa'ings ythe frame of the press comprises a hase --A,side ineinhers wB-Lllm whieh are composed of bottoni plates -fs-(-M,uprights ml)-I)-l)2--- an'd top plates 1F-M; these parts of each sidemember being east as integral parts of eaeh other. 'The side members -BIY-'M are connected together transversely at the center by a brat-e Y F-bolted to the central uprights D'-D of the side members. This brave hasa rectangular opening --G tl'ierein through ,vhieh the pitinan and:onnet-ting rods. hereinafter referred to, operate. 'the side membersare bolted to the hase f--A-Y- and to the transverse brace if eeeurely,to form a strong, firm, non vibrating support for the moving members oi"the press. On the inside of the top plates dml'--All-M, and just abovethe bottom edges thereof. there aregiiifleivays -l--leand bracketsYewl-- east thereon.

The bed 555 irs furthersupported hy central rollers i`l-7---Sw-$- (only one of the latter heingshown) .v ich are mounted on short shafts in the toi-lied upper ends ot'the adjustalle plates il lo, On these rollers the llrine'etl leises ol'the long itudiiral ribs vrtlfwlfn ot the hed restV and move when the hedis rwiproeated.

"the :wliustahle plates eQ-lOf are Conwei; l with the brave WWF-m hybolts passed thy-egli slot* iu the plates and screwed into the saidbrace so that these plates are susceptible of vertical adjustment. Thebases ot the adjustable plates are connected with the upper ends hyset-screws --13f-14-, soeketed in the brackets --15-l6-- connected 'withthe brace. Iy means of these sotsereivs the Central rollers -7-77-v8*8au he adjusted to the bottoms of tbe ribs -ll--1--- and thus furnish afirm, and suh stanti-.illy t'rietionless, support for the bed at theCenter.

Natl mozfamcat.-fl`l1e hed is pivot ally oon'- neoted at the rear withupright levers --l7--1t5A by coupling the shaft. steve to the leverswhich are constructed to serve as pivotal bearings for the said shaft.These levers are connected together transversely by a har --Jtlf-. Apitman connects this bar with a wrist-pin v-2lon a crankvvheel 2-mounted on a shaft Q3-- journaled aty the front of the machine in thehearings of a pillow-hloek -2-1 and a lateral projection of the upright-D- of the right-hand side member of the frame. The wrist-pin islengt-hened so as to. project through the pitmau connection and into andf through a hearing w in the end of an arm m(Ztl-ou a shaft 27mjournaledin hearings in the pillow-block -24ge and a lateral projection of theupright -DN on the left-hand side of the machine. This -constructionfurnishes support for the Wristpiu? at both ends, thereby giving a Ermand steady connection of the pitman With the crank-wheel which eonduoesto the easy and comparatively noiseless movement of the bed. The lowerends of the levers --17-18- are fuleruined on a transverse bar --2S, andthis bar is coupled to an adjustable vibrating link 29- mounted on a bar30-d supported in the lower parts of the pillowblocks -24-24.

The crank-Wheel -22- meshes with a driving pinion 3L- which is mountedon the driving shaft -S which is journaled in hearings in lateralprojections of the central uprights --1)D-of the side frames. Thedriving shaft carries on one end fast and loose pulleys --32--3-. Thecrankwheel @22e is rotated by the driving pinion -3l-- and through thepitman QO- vibrates or oseillates the levers l (-18-, and this, in turn,reciprocates the type or form bod -H-.

The sides of the bed have connected with them horizontal rack-bars-34-34 and Vthese rack-hars are provided with 1ongitudilnal flanges-35-35- that project, lunder similar but opposing flanges --36-36-- onplates 3?37- bolted to the side members of the frame. The bed is thusheld against vertical displaeement, between the guideways -1-1- and theflanges 36- 3b ot plates --3737-.

on its backward motion, the cylinder is rotated to the left.

The reciprocating motion of the cylinder is produced by the pinions--42-42- cn-y `:raging the stationary rack-bars -43-43-. Vhen the bedmoves forward and the cylinder turns on its axis, the pinionsI L12-42being in mesh with the teeth of the rack bars --l3l3-, the cylinder andthe crossheads SQ--ABO are. forced to move backward. The bed and thecylinder are thus moved away from a fixed point at the same time, in oposite directions at the same speed, whereiiy the distance traveled hythe bed duringl both its printing and return movement is reducedone-half, the remainder of the movement necessary for making animpression being accomplished by'the backward movement of the cylinder.

By reason of the fact that the cylinder is mounted in independent crossheads 89-39 arranged to reciprocate in the frames J-J at the oppositesides of the, machine, the said frames may be made of a minimum lengthand thereby given the maximum strength and stiffness for a given weightof metal, it being observed that. the upper members 40 of thtl frames.le-wl are required to take the entire strain of the impression. `As theslightest spring of these members 4() would give rise to an unevennessin the impressions it is important that said members should be madeextremely rigid. This is rendered possible without unduly increasingtheir size by keeping their length as short as possible for a givenlength of travel of the impression cylinder. Another important featureof the construction resides in the arrangement of the fixed racks 43outside of the frames J--J so that the bearings for the impressioncylinder may be arranged close as possible to the ends thereof. Byreason of this construction undue spring of the shaft of the impressioncylinder under the force of the impressions is avoided. Anotherimportant feature of this construction consists in the arrangement ofthe fixed racks 43 upon the frames J--J so that said racks althoughfixed against longitudinal movement rise and fall with the frames andthereby remain in full mesh with the pinions 42 on the ends of thecylinder shaft. All lost. motion between these racks and pinions isthereby avoided. yIf the racks were fixed on the frame the pinions wouldbe moved partly out of mesh therewith when the cyli s. is raised on thereturn stroke and this los Anotion would be added to the lost motionbetween the gears 73 and the racks 3l and would be `far moreobjectionable than the latter lost motion because of the smaller size ofthe pinions 42 as compared with thc gears 7 3.

form-rollers means of links -77"--77a. The caliriage travels backwardand forward in front of and With the cylinder. The ink-fonntain -78- isfastened to the rear end of the frame just below the top` The fountain--roller -79- is fitted with a ratchet-wheel on the end of its shaft andon the endfof the same shaft outside of the fono tain, an arm---lcarrying a pawl --S v is mounted and has a pin w83-H, on the endpposite the pawl, which is engaged oy a pitman 84- pivoted to acranlopin v '52 on a slide --86-' held in guides w on the outside of acam S8 By the re\ oln tion of the said cam a ret-,iprocating motion isgiven to the pitman Mirtha and lle.: pit

man, in turn, swingslhe arm and causes the pawl -S2- to engage the teethof the ratchet-wheel 0-- and thus rotate,

intermittently, the foiintaiirroller. The cvtent of the movement of tht`tonni:':irl-i'oller by the swing of the arm is` of course, gm.: erned bythe distance of the crankpm -S5- from the center of the cam -S8-. In theextended side walls of the fountain near the bottom; and between thefountain roller and the frame of the press, a shaft -SSL- is journaledin suitable bearings. This shaftI carries two upright. arms --90-- 90 inthe upper ends of which are bearings for the gudgeons of a supply-rollerfill-W. The shaft -89- also carries at one end a pendent arm O2-- fittedwith a roller h93- that bears against the face of the cam on therighbhand side of the press, which isy mounted on a shaft. 94- jennnaled in bearings in the rear uprights "-172- of the side framesA--lif-l3-. The shaft --94 also carries on the same side and behind thecam a spur-wheel -95-- which is in gear with an idle-wheel ANL- on astub-shaft bQ7-w that carries also a sprocket-wheel -98 connected bymeans of a sprocket-chain 99 with a sprocketwheel -100 Tin the drivingshaft -S-. The idlewlieel is in gear with a pinion -101 on the ,end of atransverse shaft -100 mounted in bearings in the uprights just below thetop of the frame, This sha t carries between the side frames atnansferroll -l()3-. The supply-roll --91- carries the ink from thefountaiuroller to the transfer-roll, when it is swung over b v means ofthe cam -88-. To the top plates -E-E- on both sides and just over theuprights D2- b 'ackets -l0-` 104:- are bolted which project rearwardrofser? Y with the pin -118a-; but if the feeding is intermittedaccidentally or purposely, the grid end of the arm drops down throughthe grid in the plate by gravity and the prop is swung over so that itsshoulder will arrest the downward movement of the arm of the bell-cranklever 118- and thereby the reach-rod will beheld up with its notch istdisengaged from the pin -72-, the cylinder depressing mechanism thrownout of gear and the cylinder retained in its upper position out ofcontact with the form during its forward movement.

The prop is swung back to withdraw the shoulder from under the pin-1l8awhen the cylinder begins its return movement to-V ward thefeed-board, so that the arm of the bell-crank lever can drop, and thuslower the reach-rod, so that its notch rengages the stud on the rocker,and thus couples up the cylinder depressing mechanism in time to pullthe cylinder down on its next rearward or printing movement, if thefeeding has been resumed. To accomplish this the arm 119a is positivelyconnected with the upper end of the inclined bar 119b by a pin 124 onits end which is entered into a slot 124a in the said bar so that whenthe bar is drawn down by the cam 120, the

shaft 114C will be positively rocked in such` Idirection as to swingback the prop 117 from its active position with relation to the lever118. When the parts are in this position, the arm 122 will be elevatedto the position shown in Figs. 1 and 3 and in full lines in Fig. 9. Whenthere isa sheet on the feed board and the bar 119" isreleased by the cam120, the downward movement of the grid 122a at the endof the arm 122 islimited by contact with the sheet, this being the intermediate positionindicated by the dotted lines in F ig. 9. Then the movement of the armis thus limited by the sheet, the spring 121b that holds the roller onthe inclined bar 119b against the face of the cani 120 lifts the barwithout applying any pressure tothe/arm 122 by reason of the slot 1211ainfthe bar which moves idly on the pin 124;, The arm 122 is thuspermitted t0 rest against the paper lightly so as not to cause it to cutthe paper between the slots. When' the arm 122 is thus arrested by thepaper. the prop 117 is prevented from re- Axurning to its activeposition and the eylinder will be pulled down to printing position. Itthere is no sheet on the feed board when `the cam 120 releases the bar119,v

the grid on the end of the arm 122 drops through the slots of 'the gridin the feed board to the lower position indicated by dotted lines inFig. 9, thereby turning the rock shaft 114'so as to move the prop 117intoactive relation to the lever 118 andthe cylinder will not be pulleddown to the printing position. On the succeeding reve lution of again.drawn down, the arm 122 elevated to the position shown in full lines inFigs. 1, 8, and 9, and the prop 117 removed. to its inactive positionthe parts being then, in position to receive the next sheet. Thesucceeding operation will depend upon whether or not the sheetissupplied as above explained. To assist the weight of the arm 122 inmoving the prop 117 and the intermediate connections and to regulate thepressure of the arm 122 on the sheet and thus adjust its pressureaccording to the strength of the paper, a pressureregulating spring 125is coiled on the shaft 114, one end being fastened to one of thebrackets 113 and the other to a collar 126 adjustably secured totheshaft so that by increasing or diminishing the tension oi the spring theforce with which the grid end of the arm bears upon the paper canbeeregulated as desired.

The stationary rack-bars -43--43- .the shaft 94 the arm 119b will be.

which engage the pinions -42-42 and reciprocate the impression cylinderare fastened to the lower members of the frames `Jmg by means of boltspassed through horizontal slots in the rack-bars so that they can beadjusted longitudinally. These rack-bars are also held against movement,

lengthwise by set-screws passed through pillars -127-127 and bearingagainst' the ends of the rack-bars.

My invention, considered in its. broader aspects, is not limited to theparticular construction herein shown and described nor to any particularconstruction by which the same has'been or may be carried into edt--`feet, various changes may be made without departing from the mainprinciples of the inventionand without` sacrificing its chief:.dvantages.
